grey area

I went to the police but they did not tell me anything convincing. Just that I should hang onto my bus ticket and show it at the border when I go out and I might not have any problems. I went back to the Canadian Embassy to see if they knew anything more concrete. They called around for me, to some bigger police and to the border where I entered and said it was lame because nobody would take responsibility, so I still have risk. One option is to return to the border where I entered and they will give me a stamp. But that is 3 hours away by bus and then I should wait for another bus to take me back here. Probably when I leave, it could be ok, they won't notice anything, but then again, they could cause trouble. I think I will go tomorrow or thursday to the border.
